IoT + More Test Panel

[ducky64]

A panel of mostly misc IoT devices, meant to be a fabrication test of the recent compiler and infrastructural changes. And the sublayout KiCad plugin.

Top-level boards:

• add BLE joystick
• replace can-adapter with OBD adapter
• add IoT rollerblinds and curtain crawler, all variations on a IoT brushed-DC motor driver
• replace IoT LED driver with a puck design and higher frequency LED drivers

Library additions:

• Change JLC postprocessing script to support merging BoMs, for panelization
• Add SeriesPowerFuse to support non-PPTC fuses
• Add base categories MagneticSensor and MagneticSwitch, distinct from Magnetometer which has a analog response
  • Add A1304 linear hall-effect sensor
  • Add AH1806 hall effect switch
• Add I2C bitbang adpater, to convert digital lines to I2C lines
• Add Nano2 fuseholder
• Add XBox Elite joystick block and footprint
• Add TPS92200 buck LED driver, higher frequency (and smaller inductor) than the current one
• Add DRV8870 DC motor driver
• Add JST XH, Molex Picoblade connectors.
• Add JST PH connector super-class.
• Add J1962 (OBDII) footprint
• Add Mp2722 bidirectional buck converter for single-cell LiIon

Fixes:

• Add optional signal_out_abs to AnalogSource.from_supply
• MCP73831: make stat output line optional
• Add CAN (TWAI) to ESP32C3

TODO:

• JstPhSmVerticalJlc should inherit JsPhSmVertical
• A1304 should be magnetometer type
• unify switching buck LED drivers
• delete I2cControllerBitBang.digital_external_from_link - unreferenced
• deprecate SeriesPowerPptcFuse
• add MP2722, possibly as separate PR
• use MP2722, in BLE joystick
• jlc_postprocess script should take and merge optional BoMs separately
• integrate buck / boost converter refactors
• future PR: clean up categories (again)

Pull Request Overview

This PR adds and updates IoT device example panels, including LED drivers, roller blinds, curtain crawlers, CAN/OBD adapters, and a BLE joystick. It also extends the JLC postprocessing script to merge multiple BOMs for panelization and includes KiCad prerouted blocks and footprint updates.

• Introduce new board topologies and connectors for various IoT devices
• Refactor example scripts to use shared connectors and dummy sinks, and update refinements
• Enhance jlcpcb_pcba_postprocess.py to support merging multiple BOM CSV files

• [nitpick] CLI options conventionally use hyphens; consider renaming --merge_boms to --merge-boms for consistency with common argparse style.

parser.add_argument('--merge_boms', type=str, nargs='*',

examples/jlcpcb_pcba_postprocess.py:186

• The new --merge_boms feature would benefit from an updated module docstring or top‐level usage comment explaining its behavior.

• [nitpick] Inline comment is a bit terse; consider clarifying that this pin is used for power‐good sensing or monitoring.

Similar PowerInConnector exists in test_iot_blinds.py; consider extracting shared connectors into a common module to reduce duplication.
